The map at the top center of the 311 Requests Dashboard allows spatial analysis of 311 request data. This analysis is possible using these tools:
•Binning
•Individual Points
•Map Extent Filtering
•Map Navigation
A. Binning
The data is displayed in hexagon shaped "bins" that group requests together. These bins display how many requests are contained within them. The colors indicate how many requests are in each bin -- the darker colored bins have more requests than the lighter colored bins.
This table beneath the illustration explains the numbered callouts in the Map View.

|
Blue Bin
|
|
The light blue bins contain larger numbers of assets (311 requests) than the white bins. NOTE: The darker the blue, the greater the number of assets.
|
|
|
White Bin
|
|
the white bins contains fewer numbers of assets (311 requests) than the blue bins.
